Becky,
Both Nicholas and Maria Elisabeth were born about 1780. They were both 30 years at the time of their marriage. I have a copy of their death records and the marriage record. All of which support their dates of birth around 1780. I think Maria Elisabetha was born about Nov 1780 but I don't recall exactly why I have that in my notes.
My direct email is
